SIGMA is an AI-powered system designed to assist judges and clerks in drafting reports, decisions, and judgments within Brazil’s TRF3 Electronic Judicial Process (PJe) system. It analyzes stored legal texts and procedural documents, identifying relevant patterns and suggesting pre-existing decision models for similar cases. By automating part of the drafting process, SIGMA helps improve consistency in judicial decisions while accelerating case processing. The system ultimately enhances productivity by reducing repetitive tasks and minimizing the risk of conflicting rulings.
